The Hedera Hardhat Example Project demonstrates how to test and deploy a Hedera smart contract using a community instance of the Hedera JSON RPC Relay. For more information about Hardhat projects check out their docs here.

🔥 Check out the step-by-step tutorial here.

• hardhat.config - The Hardhat project configuration file reqiured for the project. This includes the Hedera testnet account private key, community JSON-RPC relay URL, and defines the Hardhat tasks.

• /contracts - The folder that contains the Greeter smart contract.

• /test - The folder that contains the test file that tests the Greeter.sol smart contract.

• /scripts - The folder that contains the Hardhat project scripts.

• .env - The file that stores the environment variables like the testnet account private key and community JSON-RPC url
